30 Nov 06. A BAE Systems-led team is supporting efforts to modernize the Armed Forces’ Cargo Movement Operation System (CMOS). Used to track the receipt and movement of cargo by the U.S. Army, Air Force, Navy, and Marine Corps, CMOS is a client server based application currently maintained by the Air Force’s 754th Electronics Systems Group. The outcome of the project, produced by BAE Systems and teammates Ingenium Corporation and ResQSoft, will be a modernized, web-enabled version of CMOS that reduces maintenance costs to the Air Force and provides a more effective and accessible cargo tracking application to the joint logistics and transportation arena.
30 Nov 06. Advanced Micro Devices Inc. unveiled three new high-end computer processors as the chipmaker battles rival Intel Corp. for the “power users” that often set industry buying trends. AMD also announced aggressive pricing for the chips, known as the Athlon 64 FX-70 series, which will be sold in pairs for $599 to $999, depending on performance. The company’s previous high-end chip, the FX-62, sells for $713. Computers equipped with more than one processor typically are servers or workstations — machines meant to run business networks or crunch mountains of data — rather than consumer desktop PCs. AMD reckons such machines will increasingly appeal to what it calls “megataskers,” consumers who use their computers for several intensive applications including gaming, burning DVDs and downloading movies, often at the same time.

05 Dec 06. Vector Fields launched a major evolution of its high-frequency electromagnetic package, Concerto. Many additions to the electronic design automation (EDA) software including new and enhanced solvers, sophisticated model parameterisation and an enhanced scripting capability, provide the means to rapidly create and optimise the most complex radio and microwave designs. Concerto series 6 offers a comprehensive suite of electromagnetic design capabilities, using powerful geometric modelling to provide 2D and 3D simulation and design optimisation. Component or system models can be imported from CAD programs, or created using a powerful, built-in, 3D geometric modeller. To speed the design process, a major enhancement is the inclusion of a ‘parameterised history stream’, allowing complete models to be easily modified and replayed. This makes it easy to save portions of code, as script-like short cuts for designers who regularly create variations of similar products, such as antennas. When a design model is ready, users now have a choice of three simulation methods to characterise performance. As standard, Concerto offers a 3D Finite Difference Time Domain (FDTD) simulator, which has very broad ranging applicability. A 2D FDTD simulator for axisymmetric geometry is available with this release, allowing rotationally symmetric structures such as some horn antennas or coaxial components to be simulated extremely rapidly. A further time-saving feature comes in the form of adaptive meshing, which allows users to use the most efficient mesh resolution for the accuracy of solution required. Depending on the application, users have two further simulation options. A Method of Moments (MoM) tool provides a very good platform for simulating large environment problems such as installed antenna performance. A comprehensive suite of interactive post processing tools targeted at antenna design has been added in series 6. These include a tool for investigating coupling/immunity between multiple antennas – developed following many user requests and solving a rapidly growing design need. To this capability, series 6 adds a new Finite Element Method (FEM) tool which provides an elegant means of performing eigenvalue analysis for problems such as characterising microwave resonator and cavity designs. Together, this selection gives designers the means to choos
